Method for manufacturing the rf filter made by pps injection product |
| abstract |
The present invention relates to a method for manufacturing an RF filter using a PPS resin injection having excellent propagation characteristics by forming a plating layer on the surface of an injection molding made of PPS resin, which is an engineering plastic, without using nickel. The manufacturing method includes the steps of: 1) removing the skin layer on the surface of the PPS resin injection product; 2) expanding the interstitial pores on the surface of the PPS resin injection molding; 3) removing the glass fibers on the surface of the PPS resin injection molding through the interstitial pores and improving the surface roughness; 4) adsorbing a catalyst metal to enable electroless plating on the surface of the PPS resin injection molding; 5) plating copper on the PPS resin injection molded product to which the catalyst metal has been adsorbed in step 4); 6) Plating a protective metal on the PPS resin injection molded product plated with copper in step 5). |
